Resize versus crop
Resizing changes the width and height of the whole image. Cropping removes part of the image before resizing. This tool preserves the full frame; use an editor when you need to change the composition.
Choose dimensions carefully
Keeping the aspect ratio prevents stretching. If you unlock it, you can set any width and height, but circles and faces may look distorted. Reducing pixel dimensions usually reduces file size; increasing them cannot recreate detail that was never captured.
JPEG, PNG, or WebP
JPEG is a good choice for photographs and supports quality control. PNG preserves sharp edges and transparency but can be larger. WebP often provides a smaller modern web image, although you should check compatibility for older workflows.
Frequently asked questions
Are my images uploaded?
No. The file is read and processed in your browser using an image element and canvas.
How do I keep an image from stretching?
Leave Keep ratio enabled. Changing one dimension then calculates the other from the original aspect ratio.
Does resizing improve image quality?
Reducing dimensions can make a file faster to load. Enlarging an image cannot restore missing detail and may look soft.
Which format is best?
JPEG suits photographs, PNG suits transparency and crisp graphics, and WebP is often a compact web-friendly choice.
